A replacement rear derailleur hanger needs to match the bike application first; when two cycling accessories list the same fitment and specifications, the practical decision comes down to the configuration and listed price. Here, both choices are black aluminum-alloy hangers described for the Scott #277544 Addict RC 2020 SC-R-SW1-S carbon-frame bike application, with an approximate weight of 40g. The meaningful distinction is the $1.25 gap between their listed prices.
Quick verdict
Choose Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy for the lower listed price of USD 19.60. It carries the same stated material, color, approximate weight, part type, and Scott #277544/277544 application as its counterpart.
Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories only if its wording is the clearer match for the replacement hanger you are seeking. At USD 20.85, its stated specifications otherwise align with the Aluminum Alloy version.

Where each rear hanger wins
Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy
The Aluminum Alloy hanger wins on listed price. It is $1.25 lower while retaining the same black aluminum-alloy construction, about-40g weight, and stated Scott #277544 Addict RC 2020 SC-R-SW1-S application. For a shopper choosing strictly between these two closely matched entries, that makes it the cleaner default.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
The About 40g hanger wins only on title emphasis: shoppers focused on the approximate weight may find that wording more immediately recognizable. Its description also identifies an aluminum-alloy, black bike rear derailleur hanger for the same Scott #277544 application. Because the remaining named characteristics overlap, there is no separate feature advantage attached to the higher listed price.
Product notes
Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy
Pick the Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy when the Scott #277544 Addict RC 2020 SC-R-SW1-S application matches your need and you want the lower of the two listed prices. The description calls for aluminum alloy, black coloring, and an approximate 40g weight, while the package content is one bike rear derailleur hanger. Those are the same core details named for the competing hanger, so the USD 19.60 price is its concrete advantage. Its limitation is the specific configuration presented: one black rear derailleur hanger for the stated Scott #277544 application, rather than a choice distinguished by a different material, weight, or included quantity.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
The Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories is a sensible selection for someone who recognizes the "About 40g" title wording and is seeking the stated Scott #277544 Addict RC 2020 SC-R-SW1-S rear hanger application. It is described as a black aluminum-alloy bike rear derailleur hanger and includes one hanger, matching the key configuration of the Aluminum Alloy alternative. The constraint is straightforward: USD 20.85 is the higher listed price despite the same stated material, color, approximate weight, part type, and bike application. Choose it for its title wording, not for a listed specification difference.
Final choice by use case
For the most direct price-led choice, select Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy at USD 19.60. For shoppers who prefer the title that explicitly foregrounds the approximate 40g weight, Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories provides the same stated core configuration at USD 20.85. Since both are identified as black aluminum-alloy rear derailleur hangers for the same Scott #277544 Addict RC 2020 application, the lower-priced Aluminum Alloy option is the overall recommendation.
